Abstract :
The stability of the reduced-order models obtained using the method suggested by A. Lepschy et al. (Syst. Contr. Lett., vol.8, pp.405-10, May 1987) is analyzed. The relation between this method and the Routh approximation is pointed out. Some interesting properties related to the construction of the reduced-order transfer functions and to the evaluation of certain quadratic integrals are derived. An examples shows the practicality of the procedures
